Glutathionylation refers to the process of adding a glutathione molecule to a protein. This modification can affect the function of proteins, and it is important in regulating various cellular processes. There are several synonyms for this term, including glutathione addition, glutathione conjugation, and glutathionylation modification. These terms are often used interchangeably in scientific literature to describe the same chemical process. Understanding glutathionylation and its synonyms is important for researchers investigating protein regulation in cells and for those working to develop new treatments for diseases that involve dysregulation of protein functions.
